For a long time substances of different kinds have been placed on the market as moulded blocks set solidly in boxes or tins. These are mostly powders for toilet purposes or treatment media such as cleaners for boots and shoes and the like. The measures hitherto employed for arranging the fundamentally pulverulent contents in the box as a solid 1 moulded block present considerable difiiculvery economically. Not only does the exact measuring cause difiiculties, but frequently a great deal of the filling material is wasted during the filling operation. The ground for this resides in the fact that since the box is a vessel open at the top the pulverulent body as such is first filled into this box and the pressing effected then. More particularly is the working material Wasted when the box, as is frequently desirable, is constructed in a flange-like manner on its free annular edge or when there is a kink in the cylindrical surface of the box, which serves not only for stiffening but also as an abutment for the lid which is to be placed thereon.

The process forming the subject-matter of the present invention thoroughly obviates all these disadvantages, owing to the fact that, as is moreover customary in series work for themanufacture of moulded blocks, it fills the v pulverulent working material into the matrix belonging to the machine, in which case very accurate measuring is possible. which is to receive the working substance as a solid moulded block, is fitted over the matrix as a lid-like cover, and then the Working material, by means of a lower ram, is

pushed out 'ofthe matrix into the box, a suitable abutment being of course provided -for the latter. In this case anupper ram constitutes the abutment. The devices requi red for this purpose may be substantially of a known construction, it being merely necessary for the upper rams to be, equipped for the full reception of the box with its mouth downwards.

In a standard a mounted upon a base plate a are supported journals as for a roller 00 A and in the same plane, but not shown in the drawing, a further journal for a roller w, p shown in Figures 3 and 4, if two such sets of rollers are provided. In the same vertical plane as the shaft m is provided a journal 02 for an upper roller :12. Furthermore a worm 11'', which meshes with a worm wheel t ,'1s-

supported horizontally in the standard a. so I This worm wheel t is in fixed connection with the table t, which contains the matrix m. The worm wheel t and the table 6, are mounted upon a fixed vertical shaft 9, which at the lower end is secured in the base plate a, by 35 means of a journal q and a nut g and at the upper end is held by a neck. member a on a curved member a, which is secured to the standard a. The table t is double T-shaped in cross section, andtherefore comprises a plate or table top t, which forms a guide for the upper rams 0. To each uppenram there corresponds in the same vertical plane a lower ram '11. These lowerv rams are guided in the worm wheel t and each penetrates, in the manner shown in Figure 6,'into acylindrical bore in a member m. This piece m contains at the top the matrix m and is itself set in a cylindrical bore t in the table t. Figare provided, each of which corresponds to a lower ram u and a matrix m. The lower rams u are guided by a guide which 'surrounds the shaft 9 like a table. The displacing of the lower rams is effected by means of rails z, and at the end of the stroke a final compression pressure can be exerted in the neural way by thelower ram running-up on to i-(illers 0: m "With the lower rams there co-iiperate, in a known manner, upperrams 0. lVhile, however, in the manufacture "of ordinary moulded blocks, the upper rams likewise penetrate into the matrix, so that the pulverullent working material previously introduced into the matrix 011 the end of thelower ram is pressed within the matrix between the end faces of the two axially working rams, the pressing operation in'the case of the new process takes place outside the table matrix and inside the box, which roofs over the matrix perforation and registers therewith.

In the constructional example according to Fig. I denotes the filling arrangement. Through a filling shoe fthe working material passes intothe matrix m and reaches the end face of the associated lower ram u. The corresponding upper ram at this position is above the filling shoe. It is guided slowly downwards during this time by the rail 8 and receives below,.in its cavity k provided for the purpose, the box I) to he filled, which the ram takes from an automatic feed table t. The descent proceeds further, until at position II the upper ram has reached its lowest position. At-this position its end face bears with the box rim upon the table if. The internal cylindrical surface of the box bis flush with that of the matrix m. At this juncture, by the part 2 of the lower rail 2, the lower ram u may already be somewhat raised. During further travel of the table t in the direction of the arrow P the upper ram 0 revolving with it maintains the position it took up at II. whereas the lower ram 11- travelsupwards and guides the working material filled into the matrix m into the interior of the box I). which has its mouth downwards. Finally, at position III. the compression pressure previously begun by the rising portion 2 of the rail 2 and the preliminary pressing roller 11: reaches its maximum amount. The moulded block is now finished. It adheres in the box Z) and it, is now necessary for the lower ram a to be drawn back. For this purpose there serves the descending track w. At IV the lowest position of the lower ram is reached. At this position, held by the further horizontal portion 20 of the lower rail, the matrix,

with the lower ram, can again pass in front of the filling shoe f for the purpose of receiving therefrom a fresh filling. The quantity of the filling depends on the level of the end face of the lower ram u in the matrix m.

Beyond the position III, the upper ram 0 again travels upwards, owing to the portion 8' of the track rail 8. In order to remove the .hox I) located therein and now provided with run against a stationary cam or abutment such as a rail The pusher is thereby thrust further into the ram 0, and, with its lower end face, presses the box I) outgof the upper ram 0 and on to a delivery plate-it".

This procedure as a whole is repeated in a continuous manner for each individual one of the many matrices and associated upper and lower rams, as is known with such rotating machines.

- The longitudinal section shown in Figure 6 shows on the right hand side the placing of a lower ram it under the filling shoe 7, the. lower ram being located at the part in (F igure 3) of the track 10. ()n the left, a lower ram u runs straight on to the press roller :0 and thus reaches the'maximum ascent. The couliter-pressure is applied at this position by the roller .v' at the top, the'associated upper ram 0 running against this roller as. The guiding of the upper rams is effected by a guiding rail s engaging over the heads 0 of the upper rams, which is shown in Figure 6 partly in section and partly in outside elevation. The cross-sectional partin Figure 6 bears the reference 8 and thereby shows the relationship of this figure to Figure 3.

If itis a question of a box with an annular ledge below the outer rim, the apparatus shown in Fig. 4 is employed. It is not fundamentally different from the apparatus according to Fig. 3, only the cylindrical part y of the box bextending beyond the annular ledge enters the matrix m, which is correspondingly somewhat stepped in construction, so that the ledge cl bears upon the moulding table 1). If boxes of different thicknesses have to; be dealt with and it is not desired to employ a special moulding table If for each, it will be advisable, as shown in Fig. 5, to obtain the stepping in the matrix m by means of an auxiliary bush h.

In the apparatus according to Fig. 4 there are two pushers v for each ram head It. These run, at position IV, against the upper ram shaft guide, and thereby press the box out of the upper ram head.

The box-feeding is shown in Figure 7. It consists of a track If, to whichan outer receptacle t belongs. The discharging position is denoted by 25 The machine receives its drive through the shaft a of the worm a Upon this shaft is mounted a set of fast and loose pulleys a.
